Whites have it easier as far as the white underclass --- there isn't any "white-unity" going on, the educated, self-made, or otherwise well-off whites never feel any connection with the lazy no-good trash types. You never hear whites saying they want to "help their people". The low-class whites are on their own.
One reason why it's said so often among blacks is the perception that low-class whites are still white and therefore have a chance to make it for themselves. Rightly or wrongly, many blacks do not believe the same is possible for blacks and so low-class blacks are more in need of "help."
At the same time, many, many blacks have washed their hands of lower-class blacks so the above isn't as widespreads as it once perhaps was.
The primary problem that blacks have is a huge chunk of them have embraced victim status with the fervor of religion.
They can't achieve anything because of the history of slavery 160 years removed. The truth of it is every race and nationality has been enslaved at one point or the other.
Jews were enslaved by Egyptians, Assyrians, Romans
Celts were enslaved by Romans,
Greeks were enslaved by Romans
The Ottoman Turks enslaved everybody.
Only the Blacks continue to use it as their primary identity and their ongoing excuse.
If you are a victim you never accept that 90% of what happens in your life is your fault. Education is not bestowed by showing up. Like everything else in life it takes work.
